It is the heredity material:
Correct answer: B. DNA
- A. RNA
- B. DNA
- C. Proteins
- D. ATP (Adenosine Triphosphate)
Explanation
DNA is the correct answer because it is the primary hereditary material responsible for storing and transmitting genetic information in living organisms. It is composed of two long strands of nucleotides that form a double helix, with complementary base pairs allowing it to replicate and preserve genetic information across generations. RNA, while crucial for protein synthesis and gene regulation, does not serve as the hereditary material. Proteins carry out a variety of functions within the cell but do not store genetic information. ATP acts as an energy currency and is unrelated to genetic inheritance.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
